Around one in every eight youths in US prisons, with some as young as 12, has been sexually abused by another inmate or jail staff, a survey says.

In order to carry out our aim of raising public awareness of the existence and needs of male victims of family violence, the One in Three Campaign encourages all media, whether mainstream media, websites, blogs or social media, to widely share our material with attribution. However, use of our material by any third party is not a sign of endorsement or affiliation between that party and One in Three. In order to carry out our aim of working with governments to provide better assistance to those affected by family violence, the One in Three Campaign works actively with all sides of the political spectrum but is unaffiliated with any political party or position.
